PITTSBURG, PENNSYLVANIA, A CORPORATION OF NEW JERSEY.

CASTING APPARATUS.

Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed February 6, 1907- Serial No. 356,024.

To all whom it may concern:

Be it known that I, IoRIs R. WILLIAMS, of Lorain, Lorain county, Ohio,have invented a new and useful Improvement in Casting Apparatus, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming part of thisspecification, in which Figure 1 is a side elevation showing my improvedapparatus in position beneath the casting ladle of a ladlecrane; Fig. 2is a plan view of the same; and Figs. 3 and 4are detail views on alarger scale showing the pockets in the mold used in connection with myinvention.

The invention relates to apparatus employed in casting molten steel intoingots and the object of the invention is to provide improved means foreasily and quickly disposing of any surplus steel which remains in theladle after the ingot molds have been filled, and means by which thissurplus metal is cast in suitable shape to again be charged into theconverter or cupola.

In thedrawings, 2 represents the casting ladle which is carried by itstrunnions 3 on the trolley 4. The trolley 4 is longitudinally movable onthe jib 5 of the ladle crane, the trolley being actuated by means of thehydraulic cylinder 6. The ladle 2 is of the usual bottom pouring typeand is provided with the usual handoperated stopper mechanism 7 by meansof which the How of metal in casting is controlled by the operator.Beneath the crane jib-5 is a pouring track 8 having mold cars 9 whichcarry the ingot molds 10. A second track 11 parallels the track 8 and onthis track is a car 12 having mounted thereon a dumping mold l3 andswinging spout 14.

In casting steel into ingots it frequently occurs that surplus metalremains in the ladle after the molds have all been filled. Heretofore ithas been the usual practice to swing the ladle crane sidewise and lowerit until the bottom of the ladle is close to the floor and then todispose of this surplus metal by allowing it to flow out into the sandcovering the floor. The scrap metal resulting from this practice isunsuitable to be remelted, owing to the sand which adheres to it and itis also necessary that this scrap be broken up into pieces of such sizeas can be easily handled in removing it from the floor. This results ina loss of time in the casting or pouring operation, owing to the timenecessary in swinging and lowering the crane into and out of itsposition over the casting tracks.

In the operation of my improved apparatus, the ladle 2 having beenfilled with metal is moved on the cranejib 5 into the position showndotted in Fig. 1 and the ingot molds 10 on the mold cars 9 are thenfilled. The ladle 2 is then moved by means of the cylinder 6 into theposition shown by full lines in Fig. 1. This brings l the ladle inposition above the swinging spout 14 which is pivoted on the car 12. Thesurplus metal is then allowed to flow from the ladle into the spout andthe metal successively fills the pockets in the mold 13, the spout 14being moved on its pivot so as to bring the outer end of the spout aboveand successively in line with the empty pockets in the mold 13. Afterthe pockets in the mold have been filled and the surplus steel has beenemptied from the ladle 2, the mold 13 which is pivoted in bearings 15 onthe car 12 is then revolved by means of the hand wheel 16, allowing thepigs of cast metal to drop out of the pockets on the ground. The castpigs are thenremoved and the apparatus is in readiness to again repeatthe above described operations. By coating the mold with slurry orclay-wash before filling the pockets in the mold with metal, sticking oithe cast pigs to the mold is prevented.

The advantages of my invention will be apparent to those skilled in theart. The surplus metal remaining in the ladle is disposed of without thenecessity of shifting the position of the ladle crane. The metal is castinto pigs of suitable size and shape to be easily handled and quicklyremoved. The apparatus is simpleand easily kept in repair, the cost ofdisposing of surplus metal remaining in the ladle and the time necessaryto remove this metal is lessened, resulting in a longer time for pouringingots and an increased production for the plant.

I claim:

1. In apparatus for casting metal, the combination with a casting ladleand a track beneath said ladle, of a car on said track, a mold rotatablymounted on said car and havotally'mounted on said car and adapted to beswung on its pivot to bring the end of. the spout above the pockets insaid mold; substantially as described.

2. In apparatus for casting metal, the combination with a castingladleand a track beneath said ladle, of a car 011 said track, a moldrotatably mounted "on said car and having a plurality of pocketstherein, a pouring spout pivotally mounted on said car adapted to beswung on its pivot to bring the end of the spout above the pockets insaid mold, and means for rotating said mold to empty said pockets;substantiallyas described.

3. In apparatus for casting metal, the combination with a casting ladleand a track beneath said ladle, of a car on ing a plurality of pocketstherein and a pouring spout, pivsaid track, a mold rotatably mounted onsaid car and l on its pivot to bring the end of the spout above thepockets in said mold, and a hand wheel for rotating said mold to emptysaid pockets substantially as described.

4. In apparatus for casting metal, the combination with a casting ladleand a track beneath said ladle, of a car on said track, a mold rotatablymounted on said car and having a plurality of pockets therein, a pouringspout pivotally mounted on said car and means by which said spout isrotated on its pivot to bring its end in alinement with each pocket insaid mold; substantially as described.
